Hey,
Can anyone explain me Rank() with example ?
ALso what does Rank('fieldname' , 4,1) means??
Thanks
Can you explain which part of the explanation of the Rank function in the help file you don't understand?
You can find an example of the rank function here: Top 5 analysis using Rank fuction
The Rank function ranks the numbers. It only makes sense in a chart or inside an Aggr().

Dear nikil,
Ranking means arranging data in a order and marking them as it's level.
Ex:- Name Score Rank
A. 101 02
B. 110 01
C. 98 04
D. 99 03

Rank() function helps to display the N number (example 5,10,20..etc) of TOP/BOTTOM values in either Ascending/Dec ending Order in QlikView reports.

rank( [total] expression [, mode [, format]] )
Evaluates expression, compares the result with the result on the
other rows within the current column segment and returns the ranking
of the current row within the segment. For image charts the current
column segment is defined as it appears in the chart's straight
table equivalent.
If the chart is one-dimensional or if the expression is preceded by
the qualifier total, the current column segment is always equal to the
entire column. If the table or table equivalent has multiple vertical
dimensions, the current column segment will include only rows with
the same values as the current row in all dimension columns except
for the column showing the last dimension in the inter field sort
order.
The ranking is returned as a dual value, which in the case where
each row has a unique ranking will be an integer between 1 and the
number of rows in the current column segment.
In a case where several rows share the same ranking, the text and
number representations can be controlled as follows:
The second parameter mode specifies the number representation of
the function result
mode
0 (default)

If all ranks within the sharing group fall on the low side of
the middle value of the entire ranking, all rows get the lowest
rank within the sharing group.
If all ranks within the sharing group fall on the high side of the middle
value of the entire ranking, all rows in the group get the highest
rank within the sharing group.
If ranks within the sharing group span over the middle value of the
entire ranking, all rows in the group get a value corresponding to the
average of the top and bottom ranking in the entire column segment.
1 lowest rank on all rows in the group
2 average rank on all rows in the group
3 highest rank on all rows in the group
4 lowest rank on first row, then increment by one for each
row in the group
The third parameter format specifies the text representation of the
function result
format
0 (default)
low value&'-'&high value on all rows in the group (e.g. '3-
4')
1
low value on all rows in the group
2
low value on first row, blank on the following rows in the
group
The order of rows for mode 4 and format 2 is the determined by the
sort order of the chart dimensions.
Note Suppression of zero values is automatically disabled when this
function is used. Null values are disregarded.
Examples:
rank( sum( Sales ))
rank( sum( Sales ), 2 )
rank( sum( Sales ), 0, 1 )
